Loosr. REED roa Looms.

' Application filed February 10, 1922. Serial No. 535,441.

To all whom it mag concern:

Be it known that I, CARMIN Pomzzo, a subject of the King of Italy,residing at Paterson, county of Passaic, State of New Jersey, "haveinvented certain new and useful Improvements in Loose Reeds for Loo-ms,of which the following is a specification.

This invention relates to looms, and more especially to the reedmechanism thereof.

The invention provides a reed mechanism which not only performs theordinary func tion of beating up the fillingin the shed, but in additionis so constructed or mounted that streaks which are found in silk, whenthe loom is stopped between the point where the weaving stopped and theweaving is re sumed, are avoided. This streaking is due to the fillingor weft thread becoming slightly displaced while the loom is stopped.

The invention further provides a relatively simple, cheap, and efiicientdevice which may be readily and quickly connected to the batten framefor resiliently holding the reed frame against the batten frame.

An embodiment of the invention is illustrated in the accompanyingdrawing, in which i Figure l is a view of one side of a part of a battenframe, showing-the reed frame and reed therein, the parts being viewedfrom the shuttle side of the frame. 7

Figure 2' is atop plan view of the parts shown in Figure 1.

Figure 3 is a sectional view on the line I T I F gur s and 2- Figure itis a detail perspective view of my improved means for resilientlyholding the reed frame against the'batten frame.

Figure 5 is a front elevational view of the device and Figure 6 is across sectional view taken through the outer end of the device.

Referring to said drawings numeral 10 designates the batten frame, and12 the reed frame. The reed frame comprises the upper and lower boardsor rails 13, 1 1 and end pieces 16 connecting the upper and lower rails13 and 1 1. The upper rail 13 is usually made removable to receivedifferent reeds, and a bolt 17 having a wing nut 18 serves fordetachably fastening said upper rail 13 to the end piece 16. 20designates the reed.

The reed frame 12 is attached at its upper or lower part, to the battenframe '10, preferably at its upper part, as here shown, by means of afastening 22 permitting movement of the reed frame with relation to thebatten frame. The fastening 22 conveniently comprises a stud or pin 24in a bracket 25 on the batten frame, fitting into a hole or socket 26formed in the end piece 16 of the reed frame, the construction beingsuch that the reed frame can pivot or turn around the pins 24:.

Means are provided for resiliently hold ing the reed frame 12 againstthe batten frame, and these means preferably comprise a st'ifi" spring26, attached to a drum 28in a U shaped stirrup 29 fastened to thebracket 25 by a bolt 25 and bearing at its end against the lower part ofthe reed frame 12. The spring 26 in the construction shown, is formedwith a coiled portion 27 fitting around the drum 28 and a downwardlyextending arm 30. The drum 28 has trunnions 31 at its ends, which fit inslots 32 cut in the stirrup 29, and cotter pins 33 may serve to hold thetrunnions in said slots 32. One of the trunnions may be screw threadedto receive a nut 32, as shown, and the other trunnion may be made squareat its end to receive a wrench. To increase the tension of the spring 26and consequently its pressure on the reed frame, the drum 28 may beturned. The nut 32 when tightened serves to hold the drum 28 fromturning on its trunnions, and a set screw 35 "may also be provided for alike purpose. The spring 26 acts to hold the reed frame 12 against thebatten frame, except when said reed frame is moved away against thetension of said-spring when the reed in beating up a thread, meets theresistance of the woven fabric at the end of its beating up movement. v

Opemtion.The batten frame 10, as it reciprocates back and forth, causesthe reed 20 to beat up the filler thread in the shed against the wovenfabric, but the reed will move slightly away from the batten frame as itcompletes the beating up of the filler thread against the cloth, againstthe tension of the spring 26. As the reed 2O reverses its movementhowever, the spring 26' will return it against the batten frame.

When the loom is stopped for any purpose during the weaving of thecloth, the reed during the interruption will not allow any of thealready woven filling threads to become displaced, as it will be pressedagainst the filling thread by the spr ng 26 and any slight variation inthe position 0 the batten frame 10 less than the movement of the reedframe 12 against the tension of said spring 26', will not act to movethe reed out of holding contact with the last filler thread.Consequently when the loom restarts, there will be no irregularity inthe spacing of the filler threads, and there will be no streak in thewoven goods, such as is noticed in silk goods woven on previous looms,at the point where the first and last filler'threads meet after aninterruption or stopping of the loom. It is obvious that those skilledin the artmay vary the details of construction and arrangement of partswithout departing from the spirit of my invention, and, therefore, I donot wish to be limited to such features except as may be required by theclaims. What is claimed is:

1. In a loom, a batten frame, a reed frame having a reed thereon, andmeans for at- :taching said reed frame to said batten frame, said meanscomprising a pivotal connection between said batten frame and reedframe, and a coil spring adjacent said pivotal connection and detachablymounted on the batten frame and having one end portion pressing saidreed frame around said pivot against said batten frame, said attachingmeans permitting said reed frame to move slightly away from said battenframe 2. In a loom, a batten frame, a reed when the reed presses afiller thread against the woven fabric, said spring normally holdingsaid reed frame pressed against said batten frame.

frame having a reed thereon, and means for attaching said reed frame tosaid batten frame, said means comprising a pivotal connection betweensaid batten frame and reed frame, and a coil spring adjacent saidpivotal connection and detachably mounted on the batten frame and havingone end portion pressing said reed frame around said pivot against saidbatten frame, said attaching means permitting said reed frame to moveslightly away from said batten frame when the reed presses a fillerthread against the woven fabric, said spring normally holding said reedframe pressed against said batten frame, said spring having aCOllBd'POIlllOIl,

f' and a rotatable drumon which said coiled portion is fastened, saiddrum being adapted to be turned to adjust the tension of said spring. 7

3. In a loom, a batten frame, a reed frame having a reed thereon, andmeans for attaching said reed frame to said batten frame, saidmeans-comprising a pivotal connection between said batten frame and reedframe, and a spring pressing said reed frame around said pivot againstsaid batten. frame, said attaching means permitting said reed frame tomove slightly away from said batten frame when the reed presses a fillerthread against the woven fabric, said spring normally holding said reedframe pressed against said batten frame, said spring hav ing a coiledportion and a rotatable drum on which said coiled portion is fastened,said drum being adapted to be turned to adjust the tension of saidspring, and a U-shaped stirrup for holding said drum.

4. In a loom, a batten frame, a reed-frame having a reed-thereon, andmeans for attaching said reed frame to said batten frame,

said means comprising a pivotal connection between said batten frame andreed frame, and a spring pressing said reed frame around said pivotagainst said batten frame, said attaching means permitting said reedframe to move slightly away from said batten frame when the reed pressesa filler against the'woven fabric, said spring normally holding saidreed frame pressed against said batten frame, said spring having acoiled portioinand a rotatable drum on which said, coiled portion isfastened, said drum being adapted tobe turned to adjust the tensionof'said spring,said drum having trunnions, one of which is squared tofit a wrench.
